I logged onto my account at the FAA DroneZone this afternoon to register a new drone and found that several existing drone registrations in the inventory table were flagged as "Response required." It has to do with validating the RID registration number, which had been entered when they were registered some years ago and as recently as a few months ago. It was a simple matter to edit each and confirm the RID number, apparently no big deal.
If you have drones registered at the DroneZone, you might want to have a look at your inventory table.
